WILLIAM T. TRUAX., OF :BATTLE CR-iillili, MICHIGAN, ASSIGNOR TO UNITEDSTATES REGISTER COMPANY, F BATTLE GREEK, MICHIGAN, A CORPORATION OFMICHI- GAN.

WARM-AIR REG1STER To all who/m if may concern Be it known that I,liLLmivrrl. TRUAX, a citizen of the United States, residing at BattleCreek, in the county of Calhoun and 5 State of Michigan, have inventedcertain new. and useful Improvements in llVarm- Air Registers, of whichthe followingis a specification.

This invention relates to warm air register constructions. rIhe objectof this invention is to provide means for compelling all of the warm airas it comes through the register box to pass through the register front,preventing the streaking or marking and discoloring of the walls of theroom next about the register, as is frequently the result where theordinary register box and register front and the customary arrangementthereof are employed.

This invention comprises the provision of bendable metal strips that areattached to the walls of the box and lie inside the box until after theframe is attached, when the strips are turned over outwardly upon theframe, thus closing` the opening or joint between the box and the frame,and the usual center grating or lattice is then placed upon the stripsand secured to the frame in the ordinary manner, and the warm air mustpass entirely through the frame and grating or lattice, and cannot leakout sidewise or upwardly between the box and frame, or between the frameand lattice, and streak the adjacent walls or the paper thereon.

In the accompanying drawings are illustrated the construction andarrangement of the parts of this invention.

Of the drawings, Fig. l represents a regis ter box and register frame,front view, the grating or center open-work register plate being removedto show the bendable metal strips and their positions with respect tothe opening in the frame. Fig. 2 is a vertical section on the brokenline Q-Q of Fig. l, full size, showing the protecting strip bentforwardly and upwardly upon the inner edge portion or border of the sideof the frame, and showing also the grating or lattice ar ranged againstthe turned strip. Fig. 3 is a horizontal section upon the broken line3--3 of Fig. l, full size, showing the protective strip turned forwardlyand outwardly upon the inner side edge or border of the frame about theopening therein, and showing also the edge of the center or latticearranged on the strip whereby the strip is held between the edge of thelattice and the edge portion ofthe frame.

Throughout the drawings and description the same letter is used to referto the Same part.

Considering the drawings, the register frame A has formed upon it theraised portion a as shown in Fig. l extending about the usual openingenclosed by the frame, and next to the inner flat edge or border B ofthe frame. It will be noted that the border edge portion B of theregister frame is slightly sunken in order to receive the bendable metalsealing strip hereinafter mentioned` and to also receive and positionthe register grid or face plate, as illustrated in Figs. 2 and 3. In thecommon manner, the register frame is secured by the screws o to theregister' box referred to generally by the letter C. In Fig. 3 there isshown one of the side walls of the register box and marked D. The l wallcomprises two parallel sides of sheet metal connected by a grooved andbent edoe connection CZ. On the inside of the wall the connection dengages and clamps the edge of the bendable metal Strip E, and there isa fellow metal strip e similarly held upon the otherside of the openfront of the box as shown in Fig. l. In Fig. l. the protecting strips Eand e are shown before they have been turned outwardly upon the edge orborder B of the frame. In Fig. 3 the strip E is shown after it has beenbent forwardly through the opening in the frame A and upon the border Bof the side of the frame A.

Fig. 2 illustrates the top F of the register box C. Like the side wallD, shown in Fig. 3, the top F comprises two spaced sheets of metalhaving their edges joined by the grooved and bent connection 7". Thelower bend of the connection f clamps also the edge of the bendablestrip G, and this strip is shown bent outwardly and upwardly upon theflat border B of the top of the frame A. In the top of the register boxis the throat g through which the warm air may pass upwardly, when itcannot pass out through the frame A, and the latticed register plate H,by reason of the closing down of the swinging damper or gate J by meansof the finger lever In Figs, f2 and 3 it will be noted that the latticeor open-work register front plate H has a ilat flange, edge portion orborder la, that corresponds with the border B of the frame in extent,and it will be understood that the border it of the register platefollows the border B yof the fraine for 4the entire distance about Itheopening in the frame. The border zy is arranged against the strips E, e,and G, and the strips are thus held beu tween the edge of the latticeand the border B of the frame as shown.

The operation oi' this invention is believed to 4bereadily discerniblefrom the drawings and the foregoing explanation. After the frame A issecured to the box 'Bythe strips E, e and 'G are turned outwardlythrough the opening in the `frame and upon the border B. The open-workregister plate or lattice is Athen placed in position. Now, all the warmair must escape through the .ira-ine and .lattice if yfthe gate ordamper is swung f inwardly with respect to 'the box, or throu h y. ticeare fully sealed and no the throat g inthe top of the box, if t edamper'J is moved to close the openings in the register plate. Thejoints between thc frame and box and frame and grating or latstreakingfollows even after extended and continuous use of registers constructedin accorda-nce with this invention. It will be understood that inheating dwellings or other buildings by means of vwarnrair drawn lfromthe outside, there is unavoidably more or less dust Acarried into thewarin air piping system, although'the air Ibe ltaken from ya carefullyselected situation, and if there is any opening remaining between theregister box and the frame when those parts are finally placed inposition, after a time the walls immediately about the frame becomeunsightly and streaked with discolored radiating marks and patches. VByadequately Sealing the joint between the trame and box as set forthherein injury to the surrounding Wall surface or paper is eiectuallyprevented.

Having now described this invention, and explained the mode of its claimis In a warm air register, the combination with a register box havingwalls comprising parallel sheets of metal, a grooved connecting memberhaving bent edge portions clamping vthe edge portions oi' the saidsheets whereby the sheets and the connection am held together, aregister frame having an inner sunken border edge portion arrangedlati'vise against the bends oit the said cow necting `member, bendablesheet metal sealing strips each having a fiat portion arranged upon thesaid sunken border portion of the traine and (3o-extensive therewith,each sealing strip having a bent portion passing through the opening inthe register frame and a bent portion clamped to one of the said wallsheets by the said 'bent edge portion. ot the connect-ing member, and anopen-work front` plate havinfr a Hat edge portion arranged upon the saidflat portions oii the sealing strips which lie in the said sunken innerborder edge portions of the frame.

In testimony whereof I ailix my si mature.
